Abstract
A cutter head for a lawn mower which has a plurality of fingers arranged in two sets, one above the other, that extend forward in the direction of travel to channel grass between them. Between the fingers is a conveyor belt carrying a set of short blades moving transverse to the direction of motion of the mower for shearing the grass that is channeled by the fingers. The blades are preferably arranged at different levels to mulch the grass. Each blade is preferably split and bent to form multiple cutting edges at different levels. In one embodiment, the lower set of fingers extends farther forward than the upper set to better lift the grass for cutting. In an alternate embodiment, the upper set of fingers extends forward of the lower set and curves downwardly to lift objects out of the path of the mower. The continuous conveyor belt is conveyed around three sheaves that carry the plurality of blades and a sweeper to sweep grass from the cutter head.
